Solana: Why won’t by WSL generate a scaffold when I prompted “`npx create-solana-dapp“`. It generates a syntax error. What could be wrong?

Troubleshooting Solana DApp Template Generator

As a developer, you have probably encountered issues while creating a new Solana dapp template using “create-solana-dapp”. One common error is that it generates a syntax error when it prompts for scaffolding. In this article, we will explore the possible causes of this issue and provide step-by-step solutions.

What is the error?

The error message provided in the library “@clack/prompts” indicates that there is a syntax error in the generated code when creating the Solana dapp template:

case"submit":return${n}${color.grey(S_BAR)} ${color.dim(this.value||t.placeholder)};case"

Why won’t it work?

The problem is that “this” is not properly bound in the generated JavaScript code. In the function, “this” refers to the current instance of the object being executed. When you create a Solana dapp scaffold using “create-solana-dapp”, it generates code based on your input. However, when you run this command, it does not execute the template as intended.

Possible causes:

• Invalid template file path: Double-check that the template file path is correct. Make sure that the path to template.js or template.sol file matches the one specified in the generated code.

• Missing or invalid template parameters: Verify that all required template parameters (such as “solanaRuntime”, “scaffold”, and “contractName”) are properly defined in your input.

• Invalid input syntax: Review your input to ensure that it matches the expected syntax for Solana dapp templates.

Solutions:

• Verify template file path: Double-check the path to your template file and ensure that it matches the one specified in the generated code.

”bash

npm install @clack/prompts

npx create-solana-dapp –template=template.js

Verify template parameters



:
Ensure that "solanaRuntime" is properly defined and included in your input.
Make sure that contractName matches the expected template output.

javascript

const { solanaRuntime } = require(‘solana-program’);

// Sample input

const contractName = ‘My contract’;

// Define the solana runtime and contract name as required parameters

“

• When creating scaffolding, always use thetemplate.js' ortemplate.sol' file to generate code.

• Usenpx create-solana-dapp --template=template.js' instead of just running`create-solana-dapp’.

• If you experience issues, try upgrading to the latest library version and rerunning the command.

By following these steps and troubleshooting tips, you should be able to resolve the syntax error when creating a Solana dapp template using “create-solana-dapp.” Happy coding!
